Answer 1

To use the conversion factor of 22.7 L/mol in stoichiometric calculations involving gases, the following must be true:

The container holding the gases must be at standard temperature and pressure.

Standard temperature and pressure (STP) are defined as 0 degrees Celsius (273.15 K) and 1 atm pressure. Under these conditions, 1 mole of an ideal gas occupies 22.7 liters. This conversion factor is applicable when gases are at STP, so it's essential for proper calculations involving gas volumes.
